MP28372  
Dual 1.5A, 23V, 1.4MHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28372 is a dual monolithic step-down  
switch mode converter with built-in internal  
power MOSFETs. It achieves 1.5A continuous  
output current for each output over a wide input  
supply range with excellent load and line  
regulation.  
1.5A Current for Each Output  
0.18Internal Power MOSFET Switches  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 90% Efficiency  
40μA Shutdown Mode  
Fixed 1.4MHz Frequency  
Thermal Shutdown  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Cycle-by-Cycle Over Current Protection  
Wide 4.75V to 23V Operating Input Range  
Each Output Adjustable from 0.92V to 16V  
Configurable for Single Output with Double  
the Current  
Programmable Under Voltage Lockout  
Programmable Soft-Start  
Available in TSSOP20 with Exposed Pad  
and SOIC Packages  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown. In  
shutdown mode, the regulator draws 40μA of  
supply current.  
The MP28372 requires a minimum number of  
readily available standard external components.
